Abstract
Ribulose-1,5-bisphosphate (RuBP) carboxylase is the major stromal protein in chloroplasts from C3 plants. It performs the first step in the Calvin cycle and is composed of 8 large subunits and 8 small subunits. The large subunits, of 53,000 daltons, are encoded by chloroplast DNA and the small subunits, of 14,000 daltons, are encoded by nuclear DNA (1,2). The small subunit is synthesized as a 20,000 dalton precursor, on free cytoplasmic ribosomes (3–6). This precursor functions in the post-translational transport of the small subunit from the site of synthesis into chloroplasts (5,6).
